The Be Star Spectra (BeSS) Database
Neiner, C.; Floquet, M.; de Batz, B. +3 more
Be stars vary on many timescales, from hours to decades. A long time base of observations to analyze certain phenomena in these stars is therefore necessary. Collecting all existing and future Be star spectra into one database has thus emerged as an important tool for the Be star community. Moreover, for statistical studies, it is useful to have c…
An Ultraviolet Spectroscopic Atlas of Local Starbursts and Star-forming Galaxies: The Legacy of FOS and GHRS
Heckman, Timothy M.; Calzetti, Daniela; Leitherer, Claus +1 more
We present 46 rest-frame ultraviolet (UV) spectra of 28 local starburst and star-forming galaxies which were observed with the Faint Object Spectrograph (FOS) and the Goddard High Resolution Spectrograph (GHRS) of the Hubble Space Telescope (HST) at a spectral resolution of a few 100 km s-1. We compare the HST spectra with lower resolut…
Wind Structure and Luminosity Variations in the Wolf-Rayet/Luminous Blue Variable HD 5980
Hillier, D. John; Morrell, Nidia; Gamen, Roberto +3 more
Over the past 40 years, the massive luminous blue variable/Wolf-Rayet system HD 5980 in the Small Magellanic Cloud (SMC) has undergone a long-term S Doradus-type variability cycle and two brief and violent eruptions in 1993 and 1994. In this paper we analyze a collection of UV and optical spectra obtained between 1979 and 2009 and perform CMFGEN m…
A Search for Water Vaporization on Ceres
Carry, B.; Mousis, O.; Jehin, E. +5 more
There are hints that the dwarf planet (1) Ceres may contain a large amount of water ice. Some models and previous observations suggest that ice could be close enough to the surface to create a flux of water outward through the regolith. This work aims to confirm a previous detection of OH emission off the northern limb of Ceres with the Internatio…
Observations and Orbital Analysis of the Giant White Dwarf Binary System HR 5692
Torres, Guillermo; Latham, David W.; Stefanik, Robert P. +3 more
We report spectroscopic observations of the red giant star HR 5692, previously known to be a binary system both from other spectroscopic work and from deviations in the astrometric motion detected by the Hipparcos satellite. Earlier International Ultraviolet Explorer (IUE) observations had shown the presence of a hot white dwarf companion to the g…
